Am thinking it has something to do with B4206 being disabled. Am gonna check.

Works w/MAF. So, there must be an AutoVE set-up mistake. Finding that mistake is what I'm looking for.

AutoVE...................................

Am now in the process of going OLSD, maybe. Have tried several things & can't get the car to run rich enough to not stumble 10ft.

AutoVE fueling...

IFR tables match the ACCEL 30#ers. I reduced the trim related to voltage & zeroed the small pulse adjustment as has been noted in the EFILive sticky related to ACCEL 30# injectors. Once this was...

Thanks for the reply. The same condition is true regarding the MAP. However, the tune tool either has no trouble converting the Imperial MAP data to Metric or the tune file is simply chosing the...

Yes, (2) updates were found while checking & loaded directly after downloading the 7.5.5 software.

The stoich commanded fueling hasn't been tried with the full PCM flash. So, will try a 14.6 or 15:1 on the new flash & see what happens.

I didn't log long enough to see LTFT's because didn't want them to be part of the issue. Set it up so that they wouldn't trim the fueling. Wanted to see the STFT's only. 17:1 was only commanded as...

Thanks

Yes, understood, that is what was done. Am always nervous when doing a full PCM re-flash. 7.5.5.72 was loaded in place of the older software, including the tune file.

I tried to go back to the...

Did a full Flash 7.5.5.72 scan tool & tune tool; same result. Here is the tune file & log. Open both together & start the log (it's short). Watch the ECT on either the F9 or dahboard & watch the...

Checked both Scan tool & tune, both are 7.5.2 (build 36) only because I tried to go back to the older stuff in order to get rid of the problem. Apparently, the tune file that was re-used after the...

I re-loaded everything w/ the 7.5.5 upgrade. The LTFT's are from another log. I set it so that they wouldn't effect this one. The STFT's come on when the ECT vs MAP table hits what it believes is...

This must be a software problem becaue it only occured after I downloaded the 7.5.5 upgrade?

Here's the latest log & tune file. Run them side by side & you'll see what is noted.

Ran a side by side, tune file to log file & found that the EFILive ECT/MAP table for OL fueling is registering twice the ECT that is noted in the F9 list & the EFILive dash gauge. For this reason,...

Here is the next issue that I have encountered. STFT's dumping unwanted fuel. Don't know how to change this. Here are tune & log file. Once the STFT's start dumping fuel, she starts burning fuel...

She's fixed!


There was a wire inside the weather seal of one of the injectors that had come loose. This caused the lean condition & the fuel trims to add fuel. Confirmed the issue by looking @...

I am thinking that it's a mechanical problem, not a tuninng problem. Am in the process of tearing her down to have a look. There is a lifter tick & the fuel trims are adding fuel due to a lean...

Here's the most recent tune & log. Reducing the inj flow from 0-45kPa has improved the VE.

Problem persists. Off throttle is now OK until it is idling. While idling it Pops. Noticed bank 2...

^^
Yes, that is the case & is what we are trying to resolve here.

Along w/DFCO & the other mods, it seems to need more timing restriction & possibly an injector flow reduction. In my log you...

^^^ Thanks for the settings. Haven't loaded them yet, but will.

Here is the current tune & a log. Car now POPS or BANGS during idle. Will idle for a while & then BANG, idle some more & then...

I will later. Just got back from my garage. False alarm, it's doing the exact same thing.
Seems like once it warmed up, it got worse. So, am thinking ECT timing related.

OK, there is an improvement. Backfires immediately upon lifting. So, is the next modification to the VE, OL or other?

Thanks, I see that you richened the open loop cold fueling (VE, spark as well). The OL fueling is one area that I didn't modify because didn't think that it would help. After seeing the changes...
